Abstract
BACKGROUND Modified Runchang-Tang (MRCT), a Chinese herbal medicine, is widely used to treat functional constipation (FC), which is a common digestive system disease. However, its efficacy has not been evaluated systematically and objectively. Thus, a meta-analysis was conducted to assess the efficacy and safety of MRCT for treating functional constipation. METHODS We searched for relevant publications from Embase, Medline, The Cochrane Library, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Scientific Journals Database, and Wanfang Data for relevant literature. The timeframe of retrieval was set from the founding date of each database to July 15, 2020. RESULT A total of 26 randomized controlled trials with 2103 individuals were included in this meta-analysis. All trials were conducted in mainland China and were written in Chinese. The results showed that MRCT monotherapy provided better symptom relief in FC patients compared to prokinetic agent monotherapy (odds ratio, [OR] = 4.06), osmotic laxatives (OR = 4.39) and stimulant laxatives (OR = 2.99). Additionally, there were no obvious adverse effects in MRCT group compared with control group. CONCLUSION MRCT treatment is an efficient and safe treatment for FC. However, considering the limitations of this study, further well-designed randomized controlled trials are required to validate this conclusion.

Abstract
INTRODUCTION Small bowel capsule endoscopy (SBCE) is a non-invasive diagnostic technique whose use in inflammatory bowel disease (IBD) has spread. A panenteric capsule, PillCam Crohn's (PCC), has recently been developed. We lack information on the availability and use of the CEID and PCC in our environment. METHODS We conducted an electronic and anonymous survey among the members of the Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa (GETECCU) [Spanish Working Group on Crohn's Disease and Ulcerative Colitis] and the Asociación Española de Gastroenterología (AEG) [Spanish Association of Gastroenterology], consisting of 37 multiple-choice questions. RESULTS One hundred and fifty members participated, the majority dedicated to IBD (69.3%). 72.8% worked at centres with an IBD unit. 79% had SBCE available at their hospital, 14% referred patients to another centre; 22% had a PCC available, 9% referred patients to another centre. 79.3% of respondents with available SBCE used it in a small percentage of patients with IBD and 15.6% in the majority. The most frequent scenarios were suspicion of Crohn's disease (76.3%), assessment of inflammatory activity (54.7%) and assessment of the extent of the disease (54.7%). More than half (59.7%) preferentially used the Patency capsule to assess intestinal patency. Almost all respondents (99.3%) considered that training resources should be implemented in this technique. CONCLUSIONS SBCE is widely available in Spanish hospitals for the management of IBD, although its use is still limited. There is an opportunity to increase training in this technique, and consequently its use.

Abstract
BACKGROUND Like other combat sports, sambo has competition rules that divide athletes into categories based on gender, age and weight. Athletes in combat sports often resort to rapid weight loss (RWL) methods to be more competitive in lower weight categories and gain an advantage against lighter, smaller and weaker competitors. The aim of this study was to examine the methodology implemented by two different sambo age categories, junior and senior athletes, in order to attain RWL. METHODS The sample consisted of 103 male sambo elite athletes (seniors/juniors: age 28.5 ± 4.3/18.9 ± 0.8; height (m): 1.7 ± 0.1/1.8 ± 0.1; weight (kg): 76.3 ± 17.8/74.4 ± 16.3; BMI (kg/m2): 25.0 ± 3.8/23.7 ± 3.9) who completed a survey on RWL. RESULTS Athletes reported losing a mean of 5 kg starting approximately 12 days before a competition. The most common methodology reported by senior and junior sambo athletes was gradually increasing dieting, followed by sauna and plastic suit training. Less common methods adopted were laxatives, diuretics, the use of diet pills and vomiting. There were significant group differences for sauna and diet pill ingestion. Coaches and parents are influential people in the lives of athletes concerning the weight loss strategy to be adopted. CONCLUSIONS This study's results unequivocally confirm the prevalent practice of RWL in both senior and junior sambo athletes. Although athletes prevalently chose "less harmful" methods, there is a need to inform parents and coaches of the risks and benefits of RWL.

Abstract
To investigate the role of tannin-enriched extracts of Ecklonia cava (TEE) on the regulation of oxidative balance and laxative activity in chronic constipation, we investigated alterations after exposure to TEE, on constipation phenotypes, muscarinic cholinergic regulation, and oxidative stress responses in the transverse colons of SD rats with loperamide (Lop)-induced constipation. This extract contains high levels of total condensed tannin content (326.5 mg/g), and exhibited high inhibitory activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals. TEE treatment induced significant improvements in reactive oxygen species (ROS) production, superoxide dismutase (SOD) expression and nuclear factor erythroid 2-related factor 2 (Nrf2) phosphorylation in primary smooth muscles of rat intestine cells (pRISMCs) and transverse colon of constipation model. Also, Lop+TEE treated groups showed alleviated outcomes for the following: most stool parameters, gastrointestinal transit, and intestine length were remarkably recovered; a similar recovery pattern was observed in the histopathological structure, mucin secretion, water channel expression and gastrointestinal hormones secretion in the transverse colon; expressions of muscarinic acetylcholine receptors M2/M3 (mAChR M2/M3) and their mediators on muscarinic cholinergic regulation were significantly recovered. Taken together, these results provide the first evidence that TEE stimulates oxidative stress modulation and muscarinic cholinergic regulation when exerting its laxative effects in chronic constipation models.

Abstract
Adolescence is a stage in life characterized by important social, cognitive, and physical changes. Adolescents are vulnerable to various psychosocial disorders, including eating disorders. We aimed to investigate the association between unhealthy habits, sociodemographic characteristics, and the practice of self-induced vomiting or laxative misuse in a representative sample of Brazilian adolescent girls and boys. Data from 102,072 students who participated in the National Adolescent School-based Health Survey were analyzed using the dependent variable: presence or absence of self-induced vomiting and/or laxative misuse; independent variables: consumption of unhealthy and high-calorie food items, age during first sexual intercourse, and the use of tobacco, alcohol, and/or illicit drugs. Associations between exposure and outcome were estimated using Poisson's regression models stratified by sex, and including region, school, age group, and mother's educational history as adjustment variables. Eating ultra-processed foods and age during first sexual intercourse were associated with self-induced vomiting and laxative misuse only for girls; all other variables (consuming unhealthy foods and using legal or illicit substances) were associated with these behaviors for both sexes after applying adjustment variables. Early interventions focusing on changing unhealthy behaviors may prevent development of eating disorders in adolescents. Our findings demonstrate a strong association of many unhealthy habits with laxative misuse and self-induced vomiting practices in Brazilian adolescents.

Abstract
OBJECTIVES Female athletes experience eating disorders (EDs) at clinical, and subclinical, levels; most studies have determined point-prevalence rates through cross-sectional methodologies. To date, few studies have examined the long-term stability of EDs in female athletes; none extend into retirement. DESIGN A longitudinal investigation of ED classification (i.e., Clinical ED, Subclinical ED, Healthy) and weight control behaviors (e.g., vomiting, laxative use) from when athletes actively competed (T1) into their retirement (T2). METHODS Participants included U.S. female athletes (N=193) who were collegiate competitors (T1) and eventually were retired from their collegiate sports six years later (T2). RESULTS At T2, athletes were classified as Healthy (69.9%), Subclinical ED (26.9%), and Clinical ED (3.1%). Overall percentage of Subclinical EDs increased from 18.7% (T1) to 26.9% (T2); 52.8% of T1 Subclinical ED athletes continued to meet criteria for either Subclinical or Clinical ED at T2. Of the 13 Clinical ED athletes at T1, six (46.2%) continued to meet criteria for either a subclinical or clinical ED at T2. Though exercising (2+ hours/day; n=8, 4.1%) and dieting/fasting (4+ times/year; n=14, 7.3%) were the most frequently used weight control behaviors at T2, rates were substantially lower than at T1. CONCLUSIONS Retirement does not result in immediate remittance of eating concerns among female athletes; many continue or develop Subclinical and Clinical ED symptoms. Thus, addressing healthy body image and nutrition when athletes are competing is imperative to assist prevention and intervention efforts that may alleviate ED symptoms as athletes transition from sport.

Abstract
BACKGROUND Bowel preparation for colonoscopy is often poorly tolerated due to poor palatability and adverse effects. This can negatively impact on the patient experience and on the quality of bowel preparation. This systematic review and meta-analysis was carried out to assess whether adjuncts to bowel preparation affected palatability, tolerability and quality of bowel preparation (bowel cleanliness). METHODS A systematic search strategy was conducted on PubMed, MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews to identify studies evaluating adjunct use for colonoscopic bowel preparation. Studies comparing different regimens and volumes were excluded. Specific outcomes studied included palatability (taste), willingness to repeat bowel preparation, gastrointestinal adverse events and the quality of bowel preparation. Data across studies were pooled using a random-effects model and heterogeneity assessed using I2-statistics. RESULTS Of 467 studies screened, six were included for analysis (all single-blind randomised trials; n = 1187 patients). Adjuncts comprised citrus reticulata peel, orange juice, menthol candy drops, simethicone, Coke Zero and sugar-free chewing gum. Overall, adjunct use was associated with improved palatability (mean difference 0.62, 95% confidence interval 0.29-0.96, p < 0.001) on a scale of 0-5, acceptability of taste (odds ratio 2.75, 95% confidence interval: 1.52-4.95, p < 0.001) and willingness to repeat bowel preparation (odds ratio 2.92, 95% confidence interval: 1.97-4.35, p < 0.001). Patients in the adjunct group reported lower rates of bloating (odds ratio 0.48, 95% confidence interval: 0.29-0.77, p = 0.003) and vomiting (odds ratio 0.47, 95% confidence interval 0.27-0.81, p = 0.007), but no difference in nausea (p = 0.10) or abdominal pain (p = 0.62). Adjunct use resulted in superior bowel cleanliness (odds ratio 2.52, 95% confidence interval: 1.31-4.85, p = 0.006). Heterogeneity varied across outcomes, ranging from 0% (vomiting) to 81% (palatability), without evidence of publication bias. The overall quality of evidence was rated moderate. CONCLUSION In this meta-analysis, the use of adjuncts was associated with better palatability, less vomiting and bloating, willingness to repeat bowel preparation and superior quality of bowel preparation. The addition of adjuncts to bowel preparation may improve outcomes of colonoscopy and the overall patient experience.

Abstract
OBJECTIVES Chronic constipation (CC) is a recurrent functional bowel disorder worldwide. The purpose of this study is to examine its pooled placebo response rate and compare placebo response level in randomized controlled trials (RCTs) with different endpoint assessments. METHODS PubMed, Cochrane Library, and Embase were electronically searched for therapeutic RCTs of CC with placebo control. Data extraction and assessment of risk of bias were performed independently by 2 reviewers. All the statistical calculation and analysis were performed using R 3.6.0. Our protocol has registered in PROSPERO with registration number: CRD42019121287. RESULTS There were 46 studies included with 5,992 constipated patients allocated to the placebo arm in total. The pooled placebo response rate was 28.75% (95% confidence interval: 23.83%-33.67%) with significant heterogeneity among trials ((Equation is included in full-text article.)= 93.6%). Treatment efficacy assessed using subjective improvement had a significantly higher placebo response rate than that assessed with improvement in complete (spontaneous) bowel movements or composite improvement (41.40% vs 18.31% or 20.35%, P < 0.001). According to the results of meta-regression, active treatment and endpoint assessment were most likely to lead to the huge heterogeneity among studies. DISCUSSION Patients with CC have significant response level to placebo. Based on findings in this study, we do not recommend subjective improvement as endpoint while designing therapeutic RCTs for chronic constipated patients.

Abstract
Background and aims Inadequate bowel preparation (BP) is an unfavorable factor that influence the success of colonoscopy. Although standard education (SE) given to patients are proved useful to avoid inadequate BP. Studies concerning the effects of reinforced education (RE) on the quality of BP were inconsistent. The aim of this updated meta-analysis of randomized controlled trial was to compare the quality of BP between patients receiving RE in addition to SE and those receiving SE alone. Methods MEDLINE, EMBASE, Web of Science and the Cochrane Library were systemically searched to identify the relevant studies published through April 2019. The primary outcome was the rate of adequate BP. Subgroup analyses were conducted. Secondary outcomes included BP score, adenoma detection rate (ADR), polyp detection rate (PDR), insertion time, withdrawal time, adverse events, >80% purgative intake and diet compliance. Dichotomous variables were reported as odds ratio (OR) with 95% confidence interval (CI). Continuous data were reported as mean difference (MD) with 95%CI. Pooled estimates of OR or MD were calculated using a random-effects model. Statistical heterogeneity was accessed by calculating the I2 value. A P value less than 0.05 was considered significant. Results A total of 18 randomized controlled trails (N = 6536) were included in this meta-analysis. Patients who received RE had a better BP quality than those only receiving SE (OR 2.59, 95%CI: 2.09–3.19; P<0.001). A higher ADR (OR 1.35; 95%CI: 1.06–1.72; P = 0.020) and PDR (OR 1.24, 95%CI: 1.02–1.50; P = 0.030), shorter insertion (MD -0.76; 95%CI: -1.48-(-0.04); P = 0.040) and withdrawal time (MD -0.83; 95%CI: -1.83-(-0.28); P = 0.003), less nausea/vomiting (OR 0.78; 95%CI: 0.64–0.97; P = 0.020) and abdominal distension (OR 0.72; 95%CI: 0.68–0.92; P = 0.020) were achieved in the RE group. More patients had >80% purgative intake (OR 2.17; 95%CI, 1.09–4.32; P = 0.030) and were compliant with diet restriction (OR 2.38; 95%CI: 1.79–3.17; P<0.001) in the RE group. Conclusion RE significantly improved BP quality, increased ADR and PDR, decreased insertion and withdrawal time and adverse events.

Abstract
With a worldwide prevalence of 15%, chronic constipation is one of the most frequent gastrointestinal diagnoses made in ambulatory medicine clinics, and is a common source cause for referrals to gastroenterologists and colorectal surgeons in the United States. Symptoms vary among patients; straining, incomplete evacuation, and a sense of anorectal blockage are just as important as decreased stool frequency. Chronic constipation is either a primary disorder (such as normal transit, slow transit, or defecatory disorders) or a secondary one (due to medications or, in rare cases, anatomic alterations). Colonic sensorimotor disturbances and pelvic floor dysfunction (such as defecatory disorders) are the most widely recognized pathogenic mechanisms. Guided by efficacy and cost, management of constipation should begin with dietary fiber supplementation and stimulant and/or osmotic laxatives, as appropriate, followed, if necessary, by intestinal secretagogues and/or prokinetic agents. Peripherally acting μ-opiate antagonists are another option for opioid-induced constipation. Anorectal tests to evaluate for defecatory disorders should be performed in patients who do not respond to over-the-counter agents. Colonic transit, followed if necessary with assessment of colonic motility with manometry and/or a barostat, can identify colonic dysmotility. Defecatory disorders often respond to biofeedback therapy. For specific patients, slow-transit constipation may necessitate a colectomy. No studies have compared inexpensive laxatives with newer drugs with different mechanisms. We review the mechanisms, evaluation, and management of chronic constipation. We discuss the importance of meticulous analyses of patient history and physical examination, advantages and disadvantages of diagnostic testing, guidance for individualized treatment, and management of medically refractory patients.

Abstract
Until recently, conclusive data on clinical presentation, diagnosis and therapy of the opioid-induced constipation (OIC) were not available. Lately, some phase II and III prospective studies, evaluating the efficay of several old and new laxatives in cancer and non-cancer patients, make their mechanisms of action easier to understand and lead healthcare institutions to determine homogeneous guidelines for OIC, with the use of diagnostic and treatment algorithms. On May 2018, management recommendations from a panel of 7 European experts on OIC was published on United European Gastroenterology Journal. They discussed on different aspects of OIC: (a) definitions and diagnostic criteria; (b) pathophysiology; (c) clinical evaluation; (d) patient reported outcome measures; (e) initial standard laxatives; (f) specific treatments; (g) pragmatic recommendations. Later, a multi-disciplinary panel consisting of experts in neurogastroenterology, oncology and palliative medicine gave their external input. This statement will help clinicians to harmoniously treat OIC, according to clear guidelines, resulted from phase II and III prospective studies. Nevertheless, the constipation is rarely due to opioids consumption alone. More often, different factors contribute to induce constipation, including diet, immobility, other drugs, pain during evacuation, comorbidities, gastrointestinal obstacles, especially in advanced cancer patients. Therefore, management of OIC always needs to be tailored to the individual patient based on their overall clinical picture.

Abstract
RELEVANCE The leveling of postoperative pain, early activation of patients are the leading components of the fast-track program, providing fast recovery with good quality of life, minimizing postoperative problems. In colorectal surgery, the most important factor determining the early recovery of patients is the normalization of bowel function, the restoration of defecation rhythm. AIM To assess the possibility of using dietary fiber (arabinogalactan) in combination with lactoferrin (the drug Fibraxin, Alfa Sigma) in the complex postoperative therapy of proctologic patients, as well as to determine the effectiveness of their influence on the dynamics of rehabilitation. MATERIAL AND METHODS A non-randomized cohort comparative prospective study was conducted in two clinical groups of 100 patients operated on for proctological pathology. In the first (control) group, after the operation, venotonics were prescribed for 2-3 weeks, as well as topical preparations - for 2.5 weeks. In the second (main) group, this treatment is supplemented with the use of Fibraxin, at a dosage of 6g 1 time per day, the observation period is 4 weeks. A comparative analysis of the rates of relief of postoperative defecation disorders, as well as the effect of the drug on the dynamics of the relief of leading postoperative complaints, has been carried out. RESULTS In the main group, the best results were obtained for the main parameters analyzed, early normalization of the frequency and rhythm of bowel movements was achieved, with adequate relief of complaints of pain during bowel movements and after it. Intolerance to the drug and pathological reactions associated with its use was not. The positive effect of Fibraxin in patients with concomitant diseases of the colon, including colitis, irritable bowel syndrome, diverticular disease and chronic colonic stasis, was noted. CONCLUSION The use of the drug Fibraxin at a dose of 6g per day allows a significant influence on the course of the postoperative period in proctological patients. The inclusion of Fibraxin in the scheme of rehabilitation treatment allows to stabilize the immediate results of treatment and reliably improve long-term, due to the correction of rectal dysfunction, elimination of dysbiosis, normalization of motility, as well as potentiation of reparative and restorative processes.

Abstract
Opioid-induced bowel dysfunction wich comprises several other gastrointestinal complaints; could be highly debilitating, thus significantly deteriorating patients' quality of life. In particular, opioid-induced constipation (OIC) is the most frequent symptom. Therefore patients with haematological malignances need special attention of these disabling symptoms, which should be prevented by a correct evaluation of diet, age, intestinal habits, history of prior bowel disorders as well as constipating effects of other concomitant medication. However the occurrence of OIC during treatment with opioids requires pharmacological interventions. If these measures are not sufficient to regulate intestinal functions, required to pharmacological interventions, can be used osmotic laxatives. New emerging approved agents such as naloxone pegylate (naloxegol) indicated for the treatment of opioid-induced constipation in adult patients who have had an inadequate response to osmotic laxatives for more than 3 days in patients on opioids for at least 2 weeks. Here we report the case of patient treated with this new molecule both to test its efficacy and to dispel any doubt about the possibility of worsening of pain control linked to the use of this new molecule.

Abstract
Genistein is a naturally occurring isoflavone found in soy. Genistein has been shown to increase the open probability of the most common cystic fibrosis (CF) disease-associated mutation, ∆F508-CFTR. Mice homozygous for the ∆F508 mutation are characterized with severe intestinal disease and require constant laxative treatment for survival. This pathology mimics the intestinal obstruction (meconium ileus) seen in some cystic fibrosis patients. This study tested whether dietary supplementation with genistein would reduce the dependence of the ∆F508 CF mouse model on laxatives for survival, thereby improving mortality rates. At weaning (21 days), homozygous ∆F508 mice were maintained on one of three diet regimens for a period of up to 65 days: normal diet, normal diet plus colyte, or genistein diet. Survival rates for males were as follows: standard diet (38%, n = 21), standard diet plus colyte (83%, n = 42) and genistein diet (60%, n = 15). Survival rates for females were as follows: standard diet (47%, n = 19), standard diet plus colyte (71%, n = 38), and genistein diet (87%, n = 15). Average weight of male mice fed genistein diet increased by ~2.5 g more (p = 0.006) compared to those with colyte treatment. Genistein diet did not change final body weight of females. Expression of intestinal SGLT-1 increased 2-fold (p = 0.0005) with genistein diet in females (no change in males, p = 0.722). Expression of GLUT2 and GLUT5 was comparable between all diet groups. Genistein diet reduced the number of goblet cells per micrometer of crypt depth in female (p = 0.0483), yet was without effect in males (p = 0.7267). The results from this study demonstrate that supplementation of diet with genistein for ~45 days increases the survival rate of female ∆F508-CF mice (precluding the requirement for laxatives), and genistein only improves weight gain in males.

Abstract
BACKGROUND To evaluate the effect of probiotic supplementation on functional constipation in children. METHODS We performed electronic searches in PubMed, Embase, and Cochrane Library without language restriction to identify relevant studies from the time of inception of these databases to March 2018. The relative risk or weighted mean difference was calculated to evaluate the treatment effect of probiotics using random-effects model. RESULTS We included 4 trials reporting data on 382 children with functional constipation. Overall, there were no significant differences in treatment success (P = .697), spontaneous bowel movements per week (P = .571), fecal soiling episodes per week (P = .642), straining at defecation (P = .408), use of lactulose (P = .238), use of laxatives (P = .190), fecal incontinence (P = .139), pain during defecation (P = .410), flatulence (P = .109), and adverse events (P = .979) between probiotics and placebo. Further, the use of probiotics was associated with lower frequency of glycerin enema use (weighted mean difference -2.40, P = .004) and abdominal pain (weighted mean difference -4.80, P < .001). CONCLUSION The findings of this study suggested that the use of probiotics was associated with significant improvement in glycerin enema use and abdominal pain but did not affect the treatment success and other function indices.

Abstract
Chemoprevention represents an attractive modality against colorectal cancer (CRC) although widespread clinical implementation of promising agents (e.g. aspirin/NSAIDS) have been stymied by both suboptimal efficacy and concerns over toxicity. This highlights the need for better agents. Several groups, including our own, have reported that the over-the-counter laxative polyethylene glycol (PEG) has remarkable efficacy in rodent models of colon carcinogenesis. In this study, we undertook the first randomized human trial to address the role of PEG in prevention of human colonic neoplasia. This was a double-blind, placebo-controlled, three-arm trial where eligible subjects were randomized to 8g PEG-3350 (n = 27) or 17g PEG-3350 (n = 24), or placebo (n = 24; maltodextrin) orally for a duration of six months. Our initial primary endpoint was rectal aberrant crypt foci (ACF) but this was changed during protocol period to rectal mucosal epidermal growth factor receptor (EGFR). Of the 87 patients randomized, 48 completed study primary endpoints and rectal EGFR unchanged PEG treatment. Rectal ACF had a trend suggesting potentially reduction with PEG treatment (pre-post change 1.7 in placebo versus -0.3 in PEG 8+ 17g doses, p = 0.108). Other endpoints (proliferation, apoptosis, expression of SNAIL and E-cadherin), previously noted to be modulated in rodent models, appeared unchanged with PEG treatment in this clinical trial. We conclude that PEG was generally well tolerated with the trial failing to meet primary efficacy endpoints. However, rectal ACFs demonstrated a trend (albeit statistically insignificant) for suppression with PEG. Moreover, all molecular assays including EGFR were unaltered with PEG underscoring issues with lack of translatability of biomarkers from preclinical to clinical trials. This data may provide the impetus for future clinical trials on PEG using more robust biomarkers of chemoprevention. Trial registration: ClinicalTrials.gov NCT00828984

Abstract
Inadequate dietary fiber intake contributes to the prevalent irregularity and constipation in Western countries. Although eating adequate amounts of fibers from fiber-rich foods, foods with added fibers and dietary fiber supplements is considered the first option for improving laxation, the efficacy can vary among types of fibers. The present study is a randomized control trial that included healthy adult participants with ≤3 bowel movements/week and a habitual low dietary fiber intake in a parallel design to evaluate the benefits for laxation by supplementing the daily diet with oligofructose (Orafti® P95; OF), a fermentable source of fiber and established prebiotic (n = 49); maltodextrin was the placebo (n = 48). After a run-in phase, OF was initially provided at 5 g/day, then increased to 10 and 15 g/day with four weeks for each phase. Stool frequency (bowel movements per week) for the OF and maltodextrin (MD) groups were initially similar (3.98 ± 1.49 vs. 4.06 ± 1.48), did not change for the placebo group, but increased for the OF group with the difference significant at 15 g/day (p = 0.023). Stool consistency was similar and remained unchanged at all doses for both groups. Gastrointestinal sensations were low for both groups. Laxation benefits were especially pronounced for participants with >13 g/day habitual dietary fiber intake, with significant laxation at 10 g and 15 g OF/day (p = 0.04 and p = 0.004, respectively) A daily supplement with a short-chain inulin-type fructan derived from chicory roots, i.e., oligofructose (Orafti® P95) provided a laxation effect without causing gastrointestinal (GI) distress for healthy participants with irregularity associated with low dietary fiber intake.

Abstract
BACKGROUND AND OBJECTIVES Opioid-induced constipation (OIC) is the most common adverse effect reported in patients receiving opioids to manage pain. Initial treatment with laxatives provides inadequate response in some patients. Naloxegol is a peripherally acting µ-opioid receptor antagonist used to treat patients with inadequate response to laxative(s) (laxative inadequate responder [LIR]). A cost-effectiveness model was constructed from the UK payer perspective to compare oral naloxegol 25 mg with placebo in non-cancer LIR patients receiving opioids for chronic pain, and a scenario analysis of naloxegol 25 mg with rescue laxatives compared with placebo with rescue laxatives in the same patient population. METHODS The model comprised a decision tree for the first 4 weeks of treatment, followed by a Markov model with a 4-week cycle length and the following states: 'OIC', 'non-OIC (on treatment)', 'non-OIC (untreated)' and 'death'. Two phase III trials with a follow-up period of 12 weeks provided data on treatment efficacy, transition probabilities, adverse event frequency and patient utility. Resource utilisation data were sourced from a UK-based burden of illness study and physician surveys. A UK National Health Service and Personal Social Service perspective was adopted; costs and health-related quality of life gains were discounted at a rate of 3.5 %. The model was run over a time horizon of 5 years, reflecting the average period of opioid use. RESULTS Naloxegol has an incremental cost-effectiveness ratio of £10,849 per quality-adjusted life-year gained versus placebo, and £11,179 when rescue laxatives are made available in both arms (2014 values). Model outcomes were only sensitive to variations in utility inputs. However, the probabilistic sensitivity analyses indicate that naloxegol has a 91 % probability of being cost effective at a £20,000 threshold when compared with placebo. CONCLUSIONS Naloxegol is likely a cost-effective treatment option for LIR patients with OIC. This assessment should be supported by further work on the utility of patients with OIC, including how utility varies with more granular measures of OIC.

Abstract
AIM The aim of this review is to provide an overview of the clinical assessment and evidence-based treatment options for managing diabetes-associated chronic constipation. METHODS A literature search of published medical reports in English language was performed using the OVID Portal, from PUBMED and the Cochrane Database of Systematic Reviews, from inception to October 2015. A total of 145 abstracts were identified; duplicate publications were removed and 95 relevant full-text articles were retrieved for potential inclusion. RESULTS Chronic constipation is one of the most common gastrointestinal symptoms in patients with diabetes, and occurs more frequently than in healthy individuals. Treatment goals include improving symptoms and restoring bowel function by accelerating colonic transit and facilitating defecation. Based on guidelines and data from published literature, food and dietary change with exercise and lifestyle change should be the first step in management. For patients recalcitrant to these changes, laxatives should be the next step of treatment. Treatment should begin with bulking agents such as psyllium, bran or methylcellulose followed by osmotic laxatives if response is poor. Lactulose, polyethylene glycol and lactitol are the most frequently prescribed osmotic agents. Lactulose has a prebiotic effect and a carry-over effect (continued laxative effect for at least 6 to 7 days, post cessation of treatment). Stimulants such as bisacodyl, sodium picosulphate and senna are indicated if osmotic laxatives are not effective. Newer agents such as chloride-channel activators and 5-HT4 agonist can be considered for severe or resistant cases. CONCLUSION The primary aim of intervention in diabetic patients with chronic constipation is to better manage the diabetes along with management of constipation. The physician should explain the rationale for prescribing laxatives and educate patients about the potential drawbacks of long-term use of laxatives. They should contact their physician if short-term use of prescribed laxative fails to provide relief.

Abstract
Enduring misconceptions about the physical effects of fiber in the gut have led to misunderstandings about the health benefits attributable to insoluble and soluble fiber. This review will focus on isolated functional fibers (eg, fiber supplements) whose effects on clinical outcomes have been readily assessed in well-controlled clinical studies. This review will also focus on three health benefits (cholesterol lowering, improved glycemic control, and normalizing stool form [constipation and diarrhea]) for which reproducible evidence of clinical efficacy has been published. In the small bowel, clinically meaningful health benefits (eg, cholesterol lowering and improved glycemic control) are highly correlated with the viscosity of soluble fibers: high viscosity fibers (eg, gel-forming fibers such as b-glucan, psyllium, and raw guar gum) exhibit a significant effect on cholesterol lowering and improved glycemic control, whereas nonviscous soluble fibers (eg, inulin, fructooligosaccharides, and wheat dextrin) and insoluble fibers (eg, wheat bran) do not provide these viscosity-dependent health benefits. In the large bowel, there are only two mechanisms that drive a laxative effect: large/coarse insoluble fiber particles (eg, wheat bran) mechanically irritate the gut mucosa stimulating water and mucous secretion, and the high water-holding capacity of gel-forming soluble fiber (eg, psyllium) resists dehydration. Both mechanisms require that the fiber resist fermentation and remain relatively intact throughout the large bowel (ie, the fiber must be present in stool), and both mechanisms lead to increased stool water content, resulting in bulky/soft/easy-to-pass stools. Soluble fermentable fibers (eg, inulin, fructooligosaccharide, and wheat dextrin) do not provide a laxative effect, and some fibers can be constipating (eg, wheat dextrin and fine/smooth insoluble wheat bran particles). When making recommendations for a fiber supplement, it is essential to recognize which fibers possess the physical characteristics required to provide a beneficial health effect, and which fiber supplements are supported by reproducible, rigorous evidence of one or more clinically meaningful health benefits.

Abstract
OBJECTIVE This study was designed to investigate pharmacological interaction between magnesium laxative and antacid in patients receiving opioid analgesic. METHODS Data obtained from a total of 441 eligible patients receiving opioid analgesic for the first time were retrospectively analysed. The incidence of constipation, defined as stool-free interval of 3 days and more within the first week of opioid intake, was compared between patients who took laxative alone and those who received laxative in combination with antacid. KEY FINDINGS Laxatives were prescribed in 74% of patients, among them 61% received antacids such as proton pump inhibitor and H2 receptor blocker. Magnesia was the most commonly used laxative (89%). Constipation occurred in 21% and 55% of patients with and without laxatives, respectively. Antacids reversed the laxative action of lower doses (<2000 mg/day) but not higher doses (>2000 mg/day) of magnesia without affecting the effects of other laxatives. Therefore, it is suggested that both acid-dependent and acid-independent mechanisms may operate in the laxative action of magnesia, in which the former may be involved in the action of lower doses of magnesia. CONCLUSION Care should be taken to avoid the unfavourable pharmacological interaction between low doses of magnesia and antacid.

Abstract
Constipation is a common and often debilitating condition in the elderly, which may be caused by underlying disease conditions, structural abnormalities in the bowel, and a variety of medications such as anticholinergics, antidepressants, and opiates. In this review, we focus on opioid-induced constipation (OIC), which is often underrecognized and undertreated in the elderly. When opioid therapy is initiated, healthcare providers are encouraged to evaluate risk factors for the development of constipation as part of a thorough patient history. To this end, the patient assessment should include the use of validated instruments, such as the Bristol Stool Scale and Bowel Function Index, to confirm the diagnosis and provide a basis for evaluating treatment outcomes. Healthcare providers should use a stepwise approach to the treatment of OIC in the elderly. Conventional laxatives are a first-line option and considered well tolerated with short-term use as needed; however, evidence is lacking to support their effectiveness in OIC. Moreover, because of the risk of adverse events and other considerations, such as chewing difficulties and swallowing disorders, conventional oral laxatives may be inappropriate for the treatment of OIC in the elderly. Thus, the availability of new pharmacologic agents such as the peripherally acting µ-opioid receptor antagonists methylnaltrexone and naloxegol, which target the underlying causes of OIC, and the secretagogue lubiprostone may provide more effective treatment options for elderly patients with OIC.

Abstract
Aquaporins (AQPs) play important roles in the water transport system in the human body. There are currently 13 types of AQP, AQP0 through AQP12, which are expressed in various organs. Many members of the AQP family are expressed in the intestinal tract. AQP3 is predominantly expressed in the colon, ultimately controlling the water transport. Recently, it was clarified that several laxatives exhibit a laxative effect by changing the AQP3 expression level in the colon. In addition, it was revealed that morphine causes severe constipation by increasing the AQP3 expression level in the colon. These findings have shown that AQP3 is one of the most important functional molecules in water transport in the colon. This review will focus on the physiological and pathological roles of AQP3 in the colon, and discuss clinical applications of colon AQP3.

Abstract
Drug-related injury has been noted in virtually all organ systems, and recognition of the patterns of injury associated with medication enables modification of treatment and reduces the morbidity associated with the side effects of drugs. With the large number of new drugs being developed, documentation of the morphology of the changes seen as an adverse effect becomes important to characterize the pattern of injury. The pathologist is often the first to identify these abnormalities and correlate them with a particular drug. Kayexalate or sodium polystyrene sulfonate (SPS), a linear polymer derived from polystyrene containing sulfonic acid and sulfonate functional groups is used to treat hyperkalemia. It is usually administered with an osmotic laxative sorbitol orally or as retention enema. This combination has been implicated in causing damage to different parts of the gastrointestinal (GI) tract especially the colon and causes an established pattern of injury, recognizable by the presence of characteristic crystals, is presented to create a greater awareness of the Kayexalate colitis. This entity should be included in the differential diagnosis of lower GI mucosal injury in a setting of uremia and hyperkalemia.

Abstract
OBJECTIVE To compare the difference among the combined method of oral administration of forlaxand acupoint embedding therapy, the simple acupoint embedding therapy and the simple oral administration of for-lax in the clinical efficacy on diabetic constipation. METHODS One hundred and fifty patients were randomized intoa comprehensive group, an acupoint embedding group and a forlax group, 50 cases in each one. In the acupointembedding group, the embedding therapy was applied to bilateral Tianshu (ST 25), Daheng (SP 15), Shangjuxu(ST 37) and Dachangshu (BL 25), once a week. In the forlax group, forlax (polyethylene glycol) was prescribedfor oral administration, once a day, 10 g each time. In the comprehensive group, the acupoint embedding therapyand forlax were combined and the methods were the same as the first two groups. The treatment for 4 weeks wasas one session, and 2 sessions were required in the three groups. Separately, in 4 weeks, 8 weeks of treatment and2 months after treatment, the constipation symptom scores were compared among the three groups. At the end of2 sessions of treatment, the clinical efficacy and adverse reactions were compared among the three groups. In2 months after treatment, the recurrence rate was compared among the three groups. RESULTS The total effectiverate was 98. 0% (49/50) in the comprehensive group, better than 86. 0% (43/50) in the acupoint embeddinggroup and 78. 0% (11/50) in the forlax group (both P<0. 01). In the 4 weeks and 8 weeks of treatment, the con-stipation symptom scores were reduced significantly as compared with those before treatment in the three groups(all P<0. 05). The results in the comprehensive group were lower than those in the other two groups (all P<0. 05). In the 4 weeks of treatment, the scores were not different significantly between the acupoint embedding group and the forlax group (P>0.05). In 8 weeks of treatment and 2 months after treatment, the scores in the acupoint embedding group were better tan those in the forlax group (all p<0.05). There were 2 cases of drug adverse reaction in the comprehensive group, 6 cases in the forlax group and 0 case in the acupoint embedding group. The recurrence rate was 8.1% (4/49) in the comprehensive group, lower than 32.6% (14/43) in the acupoint embedding group and 59.0% (23/39) in the forlax group (both P<0.01). CONCLUSION the combined therapy of acupoint embedding and forlax achieves the better clinical efficacy on diabetic constipation and constipation symptom scores as compared with the simple acupoint embedding therapy and the oral administration of forlax the short-term efficacy of the simple acupoint embedding therapy is not different significantly from the simple forlax medication, but the long-term efficacy and safety are better than those of simple forlax medicaiton.

Abstract
INTRODUCTION Little is known about medication use among women with eating disorders in relation to pregnancy. AIMS To explore patterns of and associations between use of psychotropic, gastrointestinal and analgesic medications and eating disorders in the period before, during and after pregnancy. METHOD This study is based on the Norwegian Mother and Child Cohort Study (MoBa). A total of 62,019 women, enrolled at approximately 17 weeks' gestation, had valid data from the Norwegian Medical Birth Registry and completed three MoBa questionnaires. The questionnaires provided diagnostic information on broadly defined anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED) and recurrent self-induced purging in the absence of binge eating (EDNOS-P), along with self-reported use of medication six months before, during, and 0-6 months after pregnancy. RESULTS The prevalence of eating disorder subtypes before and/or during pregnancy was: 0.09% AN (n = 54), 0.94% BN (n = 585), 0.10% EDNOS-P (n = 61) and 5.00% BED (n = 3104). The highest over-time prevalence of psychotropic use was within the AN (3.7-22.2%) and EDNOS-P (3.3-9.8%) groups. Compared to controls, BN was directly associated with incident use of psychotropics in pregnancy (adjusted RR: 2.25, 99% CI: 1.17-4.32). Having AN (adjusted RR: 5.11, 99% CI: 1.53-17.01) or EDNOS-P (adjusted RR: 6.77, 99% CI: 1.41-32.53) was directly associated with use of anxiolytics/sedatives postpartum. The estimates of use of analgesics (BED) and laxatives (all eating disorders subtypes) were high at all time periods investigated. CONCLUSIONS Use of psychotropic, gastrointestinal, and analgesic medications is extensive among women with eating disorders in the period around pregnancy. Female patients with eating disorders should receive evidence-based counseling about the risk of medication exposure versus the risk of untreated psychiatric illness during pregnancy and postpartum.

Abstract
Anemarrhena asphodeloides processed by salt and raw product was compared including both chemical composition and laxative function in order to find the possible active substance to cure constipation. Processed and raw Anemarrhenae laxative effect on experimental constipation models was observed as well as chemical composition using UPLC-MS technology and the total sugar content was determined by phenol sulfuric acid method. Processed Anemarrhenae water extract improved excrement more than raw which has significant difference compared with the blank group (P < 0.05). On the other hand, the total ion flow spectrum showed no significant difference in most substance, but the total sugar content was significantly higher than raw product. Anemarrhenae ancient be recognized benefitting for draining body water in traditional Chinese medicine which has been lost in modern books because it is manifested as excellent laxative effect not diuretic effect. Saccharides carbohydrate may have closely relationship with this magically effect.

Abstract
AIM: To compare same-day whole-dose vs split-dose of 2-litre polyethylene glycol electrolyte lavage solution (PEG-ELS) plus bisacodyl for colon cleansing for morning colonoscopy.
METHODS: Consecutive adult patients undergoing morning colonoscopy were allocated into two groups i.e., same-day whole-dose or split-dose of 2-litre PEG-ELS. Investigators and endoscopists were blinded to the allocation. All patients completed a questionnaire that was designed by Aronchick and colleagues to assess the tolerability of the bowel preparation regime used. In addition, patients answered an ordinal five-value Likert scale question on comfort level during bowel preparation. Endoscopists graded the quality of bowel preparation using the Boston bowel preparation scale (BBPS). In addition, endoscopists gave an overall grading of the quality of bowel preparation. Cecal intubation time, withdrawal time, total colonoscopy time, adenoma detection rate and number of adenomas detected for each patient were recorded. Sample size was calculated using an online calculator for binary outcome non-inferiority trial. Analyses was based upon intent-to-treat. Significance was assumed at P-value < 0.05.
RESULTS: Data for 295 patients were analysed. Mean age was 62.0 ± 14.4 years old and consisted of 50.2 % male. There were 143 and 152 patients in the split-dose and whole-dose group, respectively. Split-dose was as good as whole-dose for quality of bowel preparation. The total BBPS score was as good in the split-dose group compared to the whole-dose group [6 (6-8) vs 6 (6-7), P = 0.038]. There was no difference in cecal intubation rate, cecal intubation time, withdrawal time, total colonoscopy time and adenoma detection rate. Median number of adenoma detected was marginally higher in the split-dose group [2 (1-3) vs 1 (1-2), P = 0.010]. Patients in the whole-dose group had more nausea (37.5% vs 25.2%, P = 0.023) and vomiting (16.4% vs 8.4%, P = 0.037), and were less likely to complete the bowel preparation (94.1% vs 99.3%, P = 0.020). Patients in the split-dose group were less likely to refuse the same bowel preparation regime (6.3% vs 13.8%, P = 0.033) and less likely to want to try another bowel preparation regime (53.8% vs 78.9%, P < 0.001).
CONCLUSION: Splitting reduced-volume PEG-ELS for morning colonoscopy is as effective as taking the whole dose on the same morning but is better tolerated and preferred by patients.

Abstract
AIM: To investigate the gastric emptying after bowel preparation to allow general anaesthesia.
METHODS: A prospective, non-comparative, and non-randomized trial was performed and registered on Eudra CT database (2011-002953-80) and on www.trial.gov (NCT01398098). All patients had a validated indication for colonoscopy and a preparation using sodium phosphate (NaP) tablets. The day of the procedure, patients took 4 tablets with 250 mL of water every 15 min, three times. The gastric volume was estimated every 15 min from computed antral surfaces and weight according to the formula of Perlas et al (Anesthesiology, 2009). Colonoscopy was performed within the 6 h following the last intake.
RESULTS: Thirty patients were prospectively included in the study from November 2011 to May 2012. The maximum volume of the antrum was 212 mL, achieved 15 min after the last intake. 24%, 67% and 92% of subjects had an antral volume below 20 mL at 60, 120 and 150 min, respectively. 81% of patients had a Boston score equal to 2 or 3 in each colonic segment. No adverse events leading to treatment discontinuation were reported.
CONCLUSION: Gastric volume evaluation appeared to be a simple and reliable method for the assessment of gastric emptying. Data allow considering the NaP tablets bowel preparation in the morning of the procedure and confirming that gastric emptying is achieved after two hours, allowing general anaesthesia.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhein is a pharmacological active component found in Rheum palmatum L. that is the major herb of the San-Huang-Xie-Xin-Tang (SHXXT), a medicinal herbal product used as a remedy for constipation. Here we have investigated the comparative pharmacokinetics of rhein in normal and constipated rats. Microarray analysis was used to explore whether drug-metabolizing genes will be altered after SHXXT treatment. MATERIALS AND METHODS The comparative pharmacokinetics of rhein in normal and loperamide-induced constipated rats was studied by liquid chromatography with electrospray ionization tandem mass spectrometry (LC-MS/MS). Gene expression profiling in drug-metabolizing genes after SHXXT treatment was investigated by microarray analysis and real-time polymerase chain reaction (RT-PCR). RESULTS A validated LC-MS/MS method was applied to investigate the comparative pharmacokinetics of rhein in normal and loperamide-induced constipated rats. The pharmacokinetic results demonstrate that the loperamide-induced constipation reduced the absorption of rhein. Cmax significantly reduced by 2.5-fold, the AUC decreased by 27.8%; however, the elimination half-life (t1/2) was prolonged by 1.6-fold. Tmax and mean residence time (MRT) were significantly prolonged by 2.8-fold, and 1.7-fold, respectively. The volume of distribution (Vss) increased by 2.2-fold. The data of microarray analysis on gene expression indicate that five drug-metabolizing genes, including Cyp7a1, Cyp2c6, Ces2e, Atp1b1, and Slc7a2 were significantly altered by the SHXXT (0.5 g/kg) treatment. CONCLUSION The loperamide-induced constipation reduced the absorption of rhein. Since among the 25,338 genes analyzed, there were five genes significantly altered by SHXXT treatment. Thus, information on minor drug-metabolizing genes altered by SHXXT treatment indicates that SHXXT is relatively safe for clinical application.

Abstract
AIM: To compare biofeedback-guided pelvic floor exercise therapy (BFT) with the use of oral polyethylene glycol (PEG) for the treatment of obstructive defecation.
METHODS: A total of 88 subjects were assigned to treatment with either BFT (n = 44) or oral PEG (n = 44). Constipation symptoms (including difficult evacuation, hard stool, digitation necessity, incomplete emptying sensation, laxative dependence, perianal pain at defecation, and constipation satisfaction), Wexner Scores, and quality of life scores were assessed after 1, 3, and 6 mo.
RESULTS: At the 6 mo follow-up, the symptoms of the BFT group patients showed significantly greater improvements compared with the PEG group regarding difficult evacuation, hard stools, digitation necessity, laxative dependence, perianal pain at defecation, constipation satisfaction, Wexner Constipation Score, and quality of life score (P < 0.05). The quality of life score of the BFT group at the final follow-up time (6 mo) was 80 ± 2.2. After a complete course of training, improvements in the clinical symptoms of the BFT group were markedly improved (P < 0.05), and the Wexner Constipation Scores were greatly decreased compared with the oral PEG group (P < 0.05).
CONCLUSION: We concluded that manometric biofeedback-guided pelvic floor exercise training is superior to oral polyethylene glycol therapy for obstructive defecation.

Abstract
We propose a new preparation method for the computed tomography colonography (CTC). This method consists of giving a small volume (400 ml) of cleansing solution on the day before the examination and the same volume of solution on the day of the examination [low volume split-dose (LVSD) method]. Using this method, we compared the volume of residual fluid in the colon, the CT value of the residual fluid, and the quality of stool tagging with those for patients undergoing the conventional bowel preparation method. Polyp detectability of the CTC using this method and the acceptability of the preparation were also investigated. The volume of residual fluid in the colon with this method was smaller than that with the conventional method. The CT value of the residual fluid with this method was higher than that with the conventional method. Visual assessment of the quality of stool tagging with this method gave similar results to those obtained using the conventional method. The sensitivities were 95% for 5-10 mm polyps and 100% for polyps larger than 10 mm. The PPVs were 91% for 5-10 mm polyps and 100% for polyps larger than 10 mm. These results appear to be as good as in previous reports. In the questionnaires, about 80% of the answers were favorable regarding the volume and the taste of laxative. We conclude that LVSD bowel preparation method for CTC maintains polyp detectability and is better tolerated.

Abstract
Most prescribed opioids exert their analgesic effects via activation of central μ-opioid receptors. However, μ-opioid receptors are also located in the gastrointestinal (GI) tract, and activation of these receptors by opioids can lead to GI-related adverse effects, in particular opioid-induced constipation (OIC). OIC has been associated with increased use of healthcare resources, increased healthcare costs, and decreased quality of life for patients. Nonpharmacologic (e.g., increased fiber uptake) and pharmacologic agents (e.g., laxatives) may be considered for the treatment and prevention of OIC. However, many interventions, such as laxatives alone, are generally insufficient to reverse OIC because they do not target the underlying cause of OIC, opioid activation of μ-opioid receptors in the GI tract. Therefore, there has been keen interest in antagonism of the μ-opioid receptor in the periphery to inhibit the effects of opioids in the GI tract. In this review, currently available pharmacologic therapies for the treatment and prevention of OIC are summarized briefly, with a primary focus on the administration of the peripheral μ-opioid receptor antagonist methylnaltrexone bromide in patients with OIC and advanced illness who are receiving palliative care. Also, clinical trial data of methylnaltrexone treatment in patients with OIC and other pain conditions (i.e., chronic noncancer pain and pain after orthopedic surgery) are reviewed. Data support that methylnaltrexone is efficacious for the treatment of OIC and has a favorable tolerability profile.

Abstract
Constipation affects 15-25% of people. Its mechanisms are various. There are constipations due to intestinal dyskinesia (functional constipation, irritated bowel syndrome), slow transit (colonic inertia), and muscular apparatus discoordination ensuring defecation (dyssynergic defecation). The treatment of different types of constipation uses prokinetics (type 4 serotonin receptor agonists, chlorine channels activators and guanylate cyclase C channel activators) or spasmolytics, among which pinaverium bromide (dicetel) has demonstrated its high efficacy. Biofeedback therapy or surgical techniques may be used. There is a need to prescribe laxatives in any type of constipation. A pathogenetic approach to treating constipation is most efficient. The paper characterizes stimulant, osmotic, volume, and emollient laxatives and agents stimulating the urge to defecate. It also gives the data of meta-analyses evaluating the efficacy of different drug groups. Particular emphasis is laid of the effect of lactulose and its first preparation--duphalac.

Abstract
AIM: To compare results of double balloon enteroscopy (DBE) procedures in pediatric and adult patients.
METHODS: The medical files of patients who underwent DBE at Gazi University School of Medicine, Ankara, Turkey between 2009 and 2011 were examined retrospectively. Adult and pediatric patients were compared according to DBE indications, procedure duration, final diagnosis, and complications. DBE procedures were performed in an operating room under general anesthesia by two endoscopists. An oral or anal approach was preferred according to estimated lesion sites. Overnight fasting of at least 6 h prior to the start of the procedure was adequate for preprocedural preparation of oral DBE procedures. Bowel cleansing was performed by oral administration of sennosides A and B solution, 2 mL/kg, and anal saline laxative enema. The patients were followed up for 2 h after the procedure in terms of possible complications.
RESULTS: DBE was performed in 35 patients (5 pediatric and 30 adult). DBE procedures were performed for abdominal pain, chronic diarrhea, bleeding, chronic vomiting, anemia, and postoperative evaluation of anastomosis. Final diagnosis was diffuse gastric angiodysplasia (n = 1); diffuse jejunal angiodysplasia (n = 1); ulceration in the bulbus (n = 1); celiac disease (n = 1); low differentiated metastatic carcinoma (n = 1); Peutz-Jeghers syndrome (n = 1); adenomatous polyp (n = 1) and stricture formation in anastomosis line (n = 1). During postprocedural follow-up, abdominal pain and elevated amylase levels were noted in three patients and one patient developed abdominal perforation.
CONCLUSION: With the help of technological improvements, we may use enteroscopy as a safe modality more frequently in younger and smaller children.

Abstract
Bowel preparation represents an essential part of CT colonography, as the accuracy of the exam is strongly related to the adequacy of colonic cleansing, and a poor bowel preparation may compromise the diagnostic quality even despite optimization of all other acquisition parameters. Residual stool and fluid in the large bowel may affect the interpretation of the exam and may increase the number of false positives and false negatives. In this regard, the majority of patients having undergone CT colonography state that bowel preparation is the most unpleasant part. Unfortunately, to date no definite consensus has been reached about the ideal bowel preparation technique, and there is great variability in preparation strategies across diagnostic centers. The purpose of this review article is to describe the development and evolution of bowel preparation techniques in order to choose the best approach for optimizing the diagnostic quality of CT colonography in each patient.

Abstract
CONTEXT The stool softener docusate is widely used in the management of constipation in hospice patients. There is little experimental evidence to support this practice, and no randomized trials have been conducted in the hospice setting. OBJECTIVES To assess the efficacy of docusate in hospice patients. METHODS This was a 10-day, prospective, randomized, double-blind, placebo-controlled trial of docusate and sennosides vs. placebo and sennosides in hospice patients in Edmonton, Alberta. Patients were included if they were age 18 years or older, able to take oral medications, did not have a gastrointestinal stoma, and had a Palliative Performance Scale score of 20% or more. The primary outcome measures were stool frequency, volume, and consistency. Secondary outcomes were patient perceptions of bowel movements (difficulty and completeness of evacuation) and bowel-related interventions. RESULTS A total of 74 patients were randomized into the study (35 to the docusate group and 39 to the placebo group). There were neither significant differences between the groups in stool frequency, volume, or consistency, nor in difficulty or completeness of evacuation. On the Bristol Stool Form Scale, more patients in the placebo group had Type 4 (smooth and soft) and Type 5 (soft blobs) stool, whereas in the docusate group, more had Type 3 (sausage like) and Type 6 (mushy) stool (P=0.01). CONCLUSION There was no significant benefit of docusate plus sennosides compared with placebo plus sennosides in managing constipation in hospice patients. Docusate use should be considered on an individual basis.

Abstract
OBJECTIVE It is unclear whether small bowel visibility in video capsule endoscopy (VCE) is enhanced by the use of bowel preparation in addition to pre-procedural fasting. The objective of this study was to clarify this issue by means of a systematic review of the literature and meta-analysis. METHODS Randomised controlled trials comparing the use of laxative bowel preparation with fasting alone were identified using a literature search. Categorical measures of treatment efficacy were extracted from qualifying studies and pooled using random-effects meta-analyses. Primary analysis compared any bowel preparation with fasting alone; subsidiary analyses assessed diagnostic yield and results for each regimen. RESULTS Eight studies were identified, using either polyethylene glycol (PEG) or sodium phosphate (NaP) based regimens. No qualifying studies were identified using other laxatives. Study quality was sufficiently high to warrant meta-analysis. Use of any form of bowel preparation yielded significantly better visibility than fasting alone (OR = 2.31; 95% CI = 1.46-3.63; p < 0.0001). Similar results were seen for diagnostic yield (OR = 1.88; 95% CI = 1.24-2.84; p = 0.023). When sub-analysed according to the treatment used, PEG-based regimens showed benefit (OR = 3.11; 95% CI = 1.96-4.94; p < 0.0001), while NaP-based regimens yielded no significant difference from fasting alone (OR = 1.32; 95% CI = 0.59-2.96; p < 0.0001). LIMITATIONS The study did not consider results from retrospective studies, nor those which did not give a categorical measure of efficacy. The impact of prokinetic and other adjunctive treatments was not considered. The results are only relevant to the most commonly used video capsule, as data for newer alternative devices have not yet been published. CONCLUSION Based on the results of this analysis, the use of bowel preparation alongside fasting is recommended for VCE. PEG-based regimens offer a clear advantage in these patients, while the currently available evidence base does not support the use of NaP. For VCE, lower volume PEG appears to be as efficacious as higher volumes traditionally used for colonoscopy preparation.

Abstract
Cod-liver oil and other marine products containing polyunsaturated fatty acids have anti-inflammatory, anti-bacterial and anti-viral effects and may be useful in the treatment of various inflammatory and infectious diseases. We developed suppositories and ointment with 30% free fatty acid (FFA) extract from omega-3 fish oil. Our purpose was to evaluate the safety of marine lipid suppositories and ointment in healthy volunteers and to explore the laxative effect of the suppositories. Thirty healthy volunteers were randomized either to a study group administrating 30% FFA suppositories and applying 30% FFA ointment to the perianal region twice per day for two weeks, or to a control group using placebo suppositories and ointment in a double blinded manner. Results: No serious toxic effects or irritation were observed. In the study group 93% felt the urge to defecate after administration of the suppositories as compared to 37% in the control group (P = 0.001). Subsequently 90% in the study group defecated, compared to 33% in the control group (P = 0.001). Conclusion: The marine lipid suppositories and ointment were well tolerated with no significant toxic side effects observed during the study period. The suppositories have a distinct laxative effect and we aim to explore this effect in further clinical trials.
